      JAX platform explicitly. tvbo maps this to JAX_PLATFORMS before JAX initialises
      (an existing JAX_PLATFORMS in the environment still wins); tvboptim then spreads
      work across that platform's devices via n_pmap/n_vmap. In a workflow kit, 'gpu'
      also makes the experiment's rule request a SLURM gres unless one is set.
